A common abbreviation is "FCP" (sort of like "NYC" for "New York City"), which 
suggests the name "America/FCP_Yucatan".  See, for example:

"After lunch, we continue south to Felipe Carillo Puerto.  Just outside FCP, the 
birds get really exciting." http://www.xenospiza.com/Yucatan.html

The Motul De Felipe Carrillo Puerto abbreviates its name as "Motul de FCP".
